The deal is done. You won't know the outcome until long after you accept delivery (a personal inspection won't necessarily reveal everything you "need" to know before you buy, will it?), so relax and roll with it.
I'm sure that it represents a substantial capital outlay, but at this point, the potential rewards of ownership should just about even out the anxiety. It may only be a case of unwarranted buyer's remorse caused by the delay between the purchase and delivery.
We wish you the best of luck and ask that you keep all of us posted with pictures of the homecoming.
(Kind of reminds me of the adoption process, in a way.)
